To all whom t nia co'n'cema Y Be it known thai/t I, P'riiICK P. MO'N- TAGNE, a citizen of the United States, residr ing` at Bourbonnais," county of Kankakee, State of Illinois, 'have invented an Iiiiprove- `ment in. Knitting-Machines, of which ,the following description, in connection with the accompanying drawing, is-a speciiication, like characters on the dra'wing repre' This invention relates a knitting mai chine of the circular type 'comprising a cybsenting like parts. f

inder yhaving a set of cylinder needles and a g concentric dial provided with a set of dial instrumentalitiesxsuch, for ehple, as dial needlescoperatmg in their action with the as a set of dial needles, is quite limited and it is of the utmos't importance that these instrumentalities shall be accuratelypositioned with inspect to the cylinder needles in order that the prop'e'rI looping functions viis may be accurately and-uniformly effected. While it is possible by'accurato construction to locate the axis of the dial parallel to thev the dial in proper vertical relation with respect to the cylinder rit is lvery `diiiicult in.

practice to assembleiiiid-adjust the dial'in accurate. position transversely of the cylinder or in a direction'normal` to the axis of. the cylinder Without disturbing the other relative locations and adjustments... I

The main purpose and object-of this invention is therefore to provide means for bodily and relatively adjusting the'dial and the cylinder' in any direction :normal to their axes without disturbing their -axial parallelism and their nelative position longitudinally or vertically. .Y

This invention s'iadap ed jfor useinvari-"I'I .ous types of knitting ma ines butv for coi'i-4 .f venience of disclosure and illustration is herein shown as embodie in a circulark'nit ring machine provided wana sa of cylinder needles anda set .of dial needles and adapted 7 6 for` the perfomance of ribbed work and'in which the machine. is provided with awell known type of doglesshead. As theinven-lIk tion is not concerned withthe construction of the general features 'ofthe machinein- 80 fcluding the dial and 'dial su portingv structure-it will be undcrstoodlt atthese parts are shown only for the purpose of disclosingthe inventionland are described only a herein hewn as a set of separate latch dial se also while theaiai .initrimenaiiaesare' forms of Idial* instrumentalities suithblefor f coperation with' the cylinder needles may )0 be employed. The separatfe latch dial needle? I ment of `this needle in electing its coper tive action with thecylindenneedles is neceef 5 sarily small in extent and it is the'efore 95;

that these' needles shall -3 culiarly necessary be located` with great accuracy in relation to the cylinder needles. fit

In the construction illustrated'the bed plate of theknitting 'machine 1 supports a 10u revoluble gear ring 2 carrying on its` lower `face gear teeth by which it is-rotated in the' usual manner. This gear rin 2 in turn supports a cam carrier 3 containm the cams cludcsa ring support T'provided with radi.

ally projecting lugs or flanges rigidly secured hy set serew's J to the arms f3.A The upper surface of this ring support is accurately formed to present a plane surface normal to the axis ofthe eylinder l'pon this plane surface is seated the projeeting flange 10 of a ring member 11 ofthe head and the lower surfaee. of' this flange is also, aeeurately formed to present a plane surl'aee..

An annular hase 1;! is secured hy set .screws 13 to theJ bottom of the ring memher l1 and projects inwardly therefrom. l'pon this -annnlar hase. is rotar-ily i'nountedA a yarn end of the dial'supportfing shaft 19 and isl screw threaded to the exteriorto the'huh guide, vcarrier 14 apertured at 15 and pro# vided with the yarn guide 1f', for the passage, ofthe yarn. A huh 1i' 4rests upon the yarn guideearrier 1-t and is keyed at 1R to. thedial supporting shafty 19 which passes,eei i.

trally up through the -yarn guide earrier and huh. sleeve 20 fits over the upper 1T. A pair of nuts Q1 are threaded upon the. upper end of the shaft l!) and' ahnt.

against the sleeve 20.' .\n annular'eover 22 rests oYer the top of the. ring memher 11 and fills up the sp:u-e'hetween the said mene.

usual dial hed 23. ed a set, of dial mstrumentalities herein 1n thisl dial het] is mountshown as separate latch needles 'l of the` general type shown inthe patent to Pope, & Randall No. LQlLSSQ. granted October il, 1917. rl`hese needles are operated hy a dial cam 25 eonneeted to a dial eam carrier Q0 rotarily mounted on the sha ft 19. l

The rotation of the dial cam carrier 2G is effected hy a connection Q'extendinff therefrom to a post 2R rising from the gear ring 2. 'l`he rotary movement of the yarn guide earrier 14. yarn guide lf3. and eover 2:2 is efl'eeted hy a suitahle eonneetion hetwe.en the yarn guide carrier 1l and the dial eain carrier 26 herein showi. as a pin 2!) extend ing .down from the former into engagement with a projection 1,0 extendingwu])wardly from the latter.

The dial supporting shaft ffl with the dial hed is held against rotation in a manner familiar in this type of meehanism. 'l`he huh ll' is radially slotted at the. hottom and in these slots slide holts 31, the slidingmovement of the holts heing controlled by lugs 3:. projecting downwardly therefrom into a cam groove 253 formed in the, upper face of the yarn guide earrier 1l. 'l`hese holts when projected outwardly hy the eam groove enter notehes or recesses 2H in the inner periphery .of the ring memher 11. The cam groove is so shaped that the holtsare in engagement with the recesses or notehes 3lexeept as the yarn guide It passes when they are successively withdrawn inwardly. Thus the huh 1T and with it the dial supporting shaft 19 is prevented from rotation with respect t0 the ring memher-l'l and eonsu-qnently with' respect to the frame of the machine.

Any desirahle vertical adjustment of .the dial strueture is etl'eeteil through the nuts 21 and the sleeve 20. An annular plate 35 is shown eonneeted h v set.I screws 36 t0 the periphery of the huh .1T and .overlapping the eover '22 to hold -the latter in place.

'l`he general eonstruetion of thc machine, will he elear from the foregoing description and. it will he seen therefrom that, they dial strut-ture may he adjusted vertically with any degree of aeeuraey. to lil'ili; i;-th54 dial instruinentalities-into the desired vertieal position and that .hy properly manufaeturing the` parts theparallelism of the axes of the dial and of the cylinderl may readily he seeured.-

The present invention is concerned with the adjustment ofthe dial .structure so as aceurately to eenteigthe dial.; with respect to the cylinder or in other words to adjust the dial in aeeurate position transversely of the cylinder or in a direetion normal to the axis of' the eylinder without disturhing the other relative locations and adjustments.A

For this purpose the ringmeniher 11 is adjustahle on the ring support 7 'the contaeting plane ahutt'ing surfaees of thesetwo mei'nlwrs restrainingr the adffusting movement so that. the only adjustment takes place; in the direction normal to the axis of the c v1' inder. This adjustment is |n-eferably secured hy a plurality here sl-iownas four set screws 3T projet-ting radially through the vertical portion ofthe ring support T with their ends ahutting against the exterior periphery of' the ring memher ll. llence. it will he seen that h v adjusting these set screws. 37 the .ring meml'ier 1ll with the entire dial structure may he shifted as required and in any direction' normal to the axis of the cyl inder without disturling the other. relative. loeat'ions' and :nl iustments. The inner ends ol' the set serews 3T are rounded and the outer periphery of' the ring memher is bev-"125 eled slightly outwardly so that Vas. thesetl serews 25T are lot-hed up the tendenc)T t0 hold the peripheral flange li' of the ring ine/mher Il snugly 'down on the upper sui'- faee of' the ring support` T. ln or'ifler to pre- 130 vent any poesibiiity of reietive rotary movev ment of the ring member 1l and ring sup'- port 7 Whiie the adjustment is 'being mede e sei: screw 38 is provided threedd into the ring support sind projecting intefed recess 39 in the ring'member 1l.

Having fully described my invention7 what claim as new and desire to secure by Letters Patent is:

A diei adjusting mechanism for knitting machines comprising 'e ring support presenting a plane guiding Surface, a. ring member.

provided with a radial projection presenting e plane guiding surface Seated on the guiding surface of the ring support end. provided with a portion havingenoutwardly and downwardly inclined outer surface .depending in said ring support, and adjusting screws extending radialiy'through seid ring support and abutting seid inclined outer surface of the ring member wiiereby the pieneguiding sul-feces of the :111g member and ring support are drawn together.

n testimony whereof, I have signed my name to this specification.
